Basics of Cryptography: An Introduction to Ordinals

Cryptography serves as the foundation for securing sensitive information and communication in today’s digital world. Before delving into the intricacies of ordinals in cryptography, it is essential to establish a solid understanding of the basics of cryptography itself.

What is Cryptography?

Cryptography is the practice of encoding and decoding information to ensure its confidentiality, integrity, and authentication. It involves the use of mathematical algorithms and techniques to transform plain text into unintelligible cipher text, which can only be deciphered by authorized parties possessing the necessary decryption keys.

The Goals of Cryptography

The primary objectives of cryptography are:

Confidentiality: Ensuring that only authorized individuals can access and understand the information.
Integrity: Verifying that the information remains unaltered during transmission or storage.
Authentication: Validating the identities of the communicating parties to prevent impersonation or tampering.

Symmetric vs. Asymmetric Cryptography

Cryptography can be categorized into two main types: symmetric and asymmetric.

Symmetric Cryptography: In symmetric cryptography, a single key is used for both encryption and decryption. The same key is shared between the sender and receiver, making it crucial to keep the key secret. Examples of symmetric algorithms include Advanced Encryption Standard (AES) and Data Encryption Standard (DES).
Asymmetric Cryptography: Asymmetric cryptography, also known as public-key cryptography, utilizes two separate but mathematically related keys: a public key and a private key. The public key is freely shared, while the private key remains confidential. Messages encrypted with the public key can only be decrypted using the corresponding private key. This system allows secure communication between parties who have never directly exchanged keys. Popular asymmetric algorithms include RSA and Elliptic Curve Cryptography (ECC).

Key Components of Cryptography

To implement cryptography effectively, several key components are essential:

Encryption Algorithms: These are mathematical functions that transform plain text into cipher text using a specific encryption key.
Decryption Algorithms: These are mathematical functions that reverse the encryption process, converting cipher text back into plain text using the correct decryption key.
Encryption Keys: These are unique and secret values used as inputs for encryption algorithms. The encryption key is known to the sender, while the decryption key is known only to the intended recipient.
Digital Signatures: Digital signatures provide a means of verifying the authenticity and integrity of digital documents. They are created using the sender’s private key and can be verified using the corresponding public key.
